Comment(by frankprindle):

 Richard, I couldn't run "1w-init bat-charge" from the USB keyboard because
 it would just run one cycle and then came back with 2 "ok" prompts (no
 clue on why). So I unplugged the USB keyboard and repeated this using just
 the XO keyboard, realizing that I could only stop it by pulling the power
 and the battery.

 The results were pretty discouraging. It charged at 1.2A for about 2
 minutes or less. When the voltage reached 7.1V, the next line said 7.5V
 and the charging had stopped (0 ma.) So the total capacity of the battery
 seems to be around 40 mah. Not a very useful battery, I would say. After
 pulling the power and battery, attempting to run with just the battery
 worked initially but the battery indicator was red and it shut down after
 about 6 minutes. I guess that's what you get out of 40 mah.

 Is there a way I can RMA just the battery? So far no sign on this XO of
 the sticky keyboard problem (oddly, as weighed by fedex, this also weighs
 a pound more than the unit I returned, and it feels a little heftier
 too!!!) and I would hate to send the whole thing back and get a second
 replacement with a good battery and another bad keyboard (I've seen
 reports on the olpcnews forum of this happening).

 Or maybe you could send me a known good battery, I could swap it in, and
 if it behaves normally, I can send you back the rogue battery; if it still
 misbehaves I can send you back the good battery and RMA the whole XO as a
 total charging system problem.
